When causing water injection time to reach the still selected water level of no show of certain numerical value (as 8min) because of reasons such as tap water cut-off, tap are not opened, hydraulic pressure is low excessively, the obstructions of water inlet valve port, be that water level controller (28) is still during access failure, then water intaking valve (27) outage, the concurrent warning of being out of order.The performance of fault alarm is that several indicator lamps glimmer simultaneously, and long the buzzing of about 10s takes place buzzer.As dish-washing machine automatic power-off protection function is arranged, then after buzzing secondary or three times, again through just outage automatically of 5min.

B, washing (rinse) circuit

When having intake selected water level, water level controller (28) is connected, and after IC receives signal, stops VS ₃Output signal, water intaking valve (27) circuit disconnects, and stops into water.The control signal of IC output simultaneously is to the bidirectional triode thyristor Vs on the motor circuit ₁And Vs ₂G utmost point circuits for triggering, this control signal is alternately exported according to the selected motor rotation period of flow selecting switch, motor (21) drives tableware rack running just forward and reversely.Washing or during rinse, the circuit of formation as shown in figure 25, formed alternately circuit when wherein representing the motor forward and backward with thick line and dotted line.

C, draining circuit

When selected wash time arrives, by the timing circuit perception in the IC, IC stops Vs ₁And Vs ₂Control signal output, the bidirectional triode thyristor Vs on draining pump or draining valve (33) circuit ₄The output control signal, Vs ₄The conducting that is triggered, alternating current is through Vs ₄Back plumbing pump or draining valve (33) power supply form the circuit shown in the thick line among Figure 27.Behind draining valve (33) electromagnetic actuation, draw the water valve that begins to rehearse, simultaneously clutch is converted to dewatering state, for dehydration is prepared.

The computer dish-washing machine has the function of automatic control water discharge time.During the IC editor, generally compiling and editing water discharge time is 1.5min, and this all just often can reach at drainage system.But when drainage system has abnormal conditions, do not fall as drainpipe, drainpipe is lifted De Taigao, draining pump or draining valve obstruction etc., and water discharge time is prolonged.If from draining begin to the time that water level controller disconnects be D, for continuing draining, total water discharge time is 2D+30s when D＜2.5min.When D 〉=2.5min, then stop draining, disconnect the concurrent warning of being out of order of draining circuit.

D, dehydration circuit

When by the determined water discharge time of IC then, if safety switch connects, then IC counterclockwise rotates to be bidirectional triode thyristor VS on the main winding circuit to motor ₂The output control signal, VS ₂The conducting that is triggered, then motor counterclockwise aspect rotation makes the clockwise aspect of tableware rack rotary dehydration through belt transmission and clutch.Work as VS ₂During for interrupted conducting, be intermittently dehydration, work as VS ₂During by continuous conducting, be normal dehydration.Form the circuit shown in the thick line among Figure 26.

E, automatic power-down circuit

(2) fuzzy program controller

The MC6805R that the fuzzy program controller (35) of this dish-washing machine can adopt MOTOROLA company to produce ₃Single-chip microcomputer, this program controller adopt light sensors turbidity, greasy dirt degree to control the throwing amount and the wash time of washing agent, the rotating time and the rotating speed of cloth consumption sensor control water level and motor.Physical relationship is seen Figure 28 fuzzy control block diagram.

The control schematic diagram of fuzzy control automatic bowl washing machine as shown in figure 29, computer plate (198), cloth quantity sensor (199), level sensor (37), optical sensor (200), cooling-water temperature sensor (201), motor (21), steel ladle (18), tableware rack (1), water intaking valve (27).

Should can make the operator under the situation of not knowing tableware amount and dirty character and degree, make dish-washing machine operate in the optimum state of water saving, economize on electricity, joint washing agent by fuzzy program controller (35).Fuzzy program controller is with MC6805R ₃Be main control chip, peripheral circuit comprises various signal detection, motor, draining valve or draining pump, water intaking valve, overvoltage/undervoltage protection drive circuit, dishwasher into operation state and time showing.

" fuzzy control " is exactly by sensor input quantity to be sampled, and through behind the fuzzy reasoning, makes fuzzy decision, goes control and handles execution unit, to finish the purpose of automatic control.Wherein the fuzzy decision of being made is according to measurement result, becomes some fuzzy rules through remarkable summary of experience, after the fuzzy mathematics of necessity is handled, deposits single-chip microcomputer MC6805R in ₃Original program of deletion and fuzzy rule in the single-chip microcomputer manufacture process deposit the fuzzy rule and the program that are suitable for this dish-washing machine in.This program controller has the fuzzy reasoning ability, can select best washing procedure according to many washing factors.The foundation of fuzzy program controller (35) fuzzy reasoning then is from sensor.The operation principle of various sensors is described below.

A, optical sensor

Optical sensor is infrared photoelectric sensor again, is made of the infrarede emitting diode of being located at the drainpipe both sides relatively and phototriode (phototransistor).It is luminous to phototriode that light emitting diode sees through cleaning solution, by phototriode the optical signal of receiving is converted to voltage, reads its magnitude of voltage by single-chip microcomputer again, measures the muddy degree of pollution of cleaning solution with this.

Because it is difficult directly detecting the pollution situation of tableware, therefore, measures the pollution situation of cleaning solution, just can measures the contaminant capacity (degree) of tableware and pollute character.When tableware was seriously polluted, cleaning solution will be seriously muddy.Otherwise tableware pollutes when slight, and then cleaning solution is not too muddy.In other words, the muddy degree of cleaning solution and tableware pollution level are closely-related.

B, cloth quantity sensor

Also be " tableware quantity sensor ".The size that how much will directly influence dish-washing machine motor (21) load of the interior tableware of Dishwasher dishware frame (1).Therefore, in tableware rack, put into tableware, anhydrous or adding under the state of low amounts of water and carry out forward and reverse several times rotation, the generation time of two ends starting voltage just can be used for detecting the tableware amount during according to the motor stall, and the cloth quantity sensor is exactly work around this principle.The schematic diagram of cloth quantity sensor as shown in figure 30.After motor was cut off the electricity supply, t just shut down through the time.In this transient process, the remanent magnetism of rotor forms a rotating excitation field, and the stator winding cutting magnetic line produces induced electromotive force in winding.The induced electromotive force of this alternation is added on the photoelectrical coupler V, make its weekly conducting once form an action of low-voltage pulse, after amplifying shaping, import single-chip microcomputer.When the tableware amount after a little while, t is short, the pulse number of formation is few; When the tableware amount for a long time, t is long, the pulse number of formation is many.What of tableware amount single-chip microcomputer can calculate according to the pulse number of input.In order to measure accurately, can make the forward and reverse rotation of motor several times, detect several times.Figure 69 is the voltage waveform at electric capacity two ends, and (331) expression tableware amount is many, (332) expression tableware amount is few, (333) pulse, (334) amplification rectification, (335) information processing, (336) tableware amount.

C, level sensor

This level sensor can be controlled water level automatically and accurately by Single-chip Controlling, is a kind of electronic type level sensor.

Level sensor structure and circuit are shown in Figure 31,32.It is made up of air inlet (202), air chamber (203), shell (204), diaphragm of rubber (205), magnetic core (206), inductance coil (207), spring (208), adjustment screw (209).Wherein, the effect of diaphragm of rubber (205) is sealed air chamber (203), be deformation with the gas pressure intensity change transitions, and magnetic core (206) is subjected to displacement; The effect of spring (208) is to be pressed on the diaphragm of rubber (205) with certain elastic force, and the linear displacement that the nonlinear change of pressure is changed into magnetic core changes, and the jitter phenomenon to magnetic core (206) plays damping action simultaneously; The magnetic core effect is to produce magnetic field, by the inductance value that changes inductance coil that moves about it; Inductance coil (207) is formed the LC oscillating circuit with electric capacity, changes the frequency of oscillation of its vibrating circuit by the variation of inductance coil (207) inductance value; Adjust screw (209) and can adjust the precision of level sensor (37).The interior element of chain-dotted line frame is installed on the level sensor shell in Figure 32 circuit, and circuit is by phase inverter 1,2, resistance R in the frame of broken lines ₁, R ₂, capacitor C ₁, C ₂, inductance coil L forms basic LC oscillation circuit.The nonnumeric pulse signal that phase inverter 3 is exported oscillating circuit is transformed into data signal and is input among the single-chip microcomputer IC.Phase inverter the 1,2, the 3rd, digital circuit, when input was high level, output was a low level; Otherwise when input was low level, output was a high level.Because R ₁, R ₂Two resistance are added in phase inverter 1,2 input and output two ends, the phase inverter operating characteristic is changed, and make this circuit working in linear amplification region.This circuit has nearly 10 times of amplifications to input signal.

The LC oscillating circuit is connected behind the power supply just starting oscillation, if anhydrous in the steel ladle (18), then to export one-period be the oscillator signal of 16.7KHz fixed frequency to A point, makes B point identical square-wave signal of output cycle by phase inverter 3.This signal is input in the single-chip microcomputer Z/O mouth, detects judgement by single-chip microcomputer.Its A point and B point waveform are as shown in figure 33.

For the different water levels of dish-washing machine, level sensor (37) all has corresponding with it frequency pulse signal output.In the injecting process, when the pulse signal of level sensor output is stored in frequency in the single-chip microcomputer when identical with selected, the single-chip microcomputer judgement has reached requirement water level amount, and dish-washing machine stops water filling, begins to carry out washing procedure.

D, cooling-water temperature sensor

Cooling-water temperature sensor is installed in steel ladle (18) bottom, is made of thermistor.By cooling-water temperature sensor, measure the instantaneous temperature conduct temperature at that time of starting switch, the water temperature when measuring the feedwater end becomes signal to input to single-chip microcomputer the temperature transition of being surveyed, for fuzzy deduction provides information.

Hall integrated circuit is equipped with in brshless DC motor inside, the corresponding pulse in rotor field when output is rotated with rotor.The transistor of this pulse control drive motors, control flows into the electric current that produces the gyromagnet field in the motor winding, and this is the main effect of speed probe.

F, current sensor

Being in proportion of the payload of motor and electric current, therefore detecting size of current just can detect the motor load size.Current sensor detects the size that flows into current of electric by detecting ohmically voltage, goes back the current detecting of the transistorized overcurrent protection of double as simultaneously.

Above-mentioned six kinds of sensors all have finished product, are made by PANASONIC, Sanyo, Toshiba.
